Maybe the Saudi royal family paid the victims to tell the DA they wouldn’t testify in court. They do have an awful lot of money to throw at a problem like this.

That leaves a trail and can encourage others, a phone call to the powers that be is much easier and far more effective both at squelching the present problem and to make it clear to the underlings (LAPD in this case) that the Saudis are untouchable and don’t embarrass them with an arrest again.

Maybe the prosecutor actually knows what will stick and what won’t. Maybe they don’t want to waste time prosecuting when they think the accused will get off scot-free, no matter how well they do their job. You think maybe a prince can afford a lawyer or two?

and this, ladies and gentlemen, is one of the benefits of having money. the more money you have, the more justice you have. which also means, less justice for those who have less money.
is that fair? depends on how much money you have. money – apparently – determines fairness and therefor justice. so you can decide: what’s more important for governing the world we live in, morals or possessions?
